1. Introduction
1.1 Description
AU9525 is a highly integrated single chip, is the second generation USB Smart Card reader controller. Highly integration enables the lowest BOM cost of USB Smart Card reader. The AU9525 supports multiple international standards including ISO7816 for IC card standard, PC/SC 1.0 for windows smart card standard, Microsoft WHQL, EMV for Europay MasterCard Visa standard and USB-IF CCID standard. And support flexible Keyboard/LCM display interface. With our embedded enhanced 8051 MCU, user can self control Keyboard/LCM display by AP. Manufacturers can easily create a higher-security Smart Card reader by deploying AU9525. The application of AU9525 can be generally applied to Smart Card read/write terminal device, such as ATM, POS terminal, Public telephone, E-Commerce, personal consumption on Internet, personal certification, prepay system, loyalty system...etc.
